The Vatican on Monday rejected the idea that people can change or choose their genders.

The document issued on the topic is the Vatican's first on gender theory, and insists on the sexual "complementarity" of men and women to make babies.

Published during LGBTQ Pride Month, the document, titled "Male and Female He Created Them," calls for a "path of dialogue" and listening on the issue of "gender theory" in education.

VATICAN CITY (Reuters) - The Vatican condemned gender theory on Monday as part of a “confused concept of freedom”, saying in a new document that the idea of gender being determined by personal feeling rather than biology was an attempt to “annihilate nature”.

LGBT rights advocates denounced the 30-page document, called “Male and Female He Created Them”, as harmful and confusing, saying it would encourage hatred and bigotry.

ROME — The Vatican on Monday released its first extensive official document on gender theory, rejecting the notion that individuals can choose their own gender identity.

The document, issued by the Vatican department overseeing Catholic education, argued that increasing acceptance of fluid definitions of gender by schools and legal systems posed a threat to traditional families and ignored the natural differences between men and women.
